Mistress Jenna had a new slave and she did not want him to mess up for her to punish him. She wanted to teach him how she wanted things to be done. So she taught him and when he did not understand what she meant, she used her dirty feet to humiliate him and punish him. She crushed his face and even inserted his foot in her mouth to gag him and by the time she was done teaching him, she knew he would not mess up.
